Safety and efficacy of the remodelling technique in the treatment of ruptured and unruptured intracranial aneurysms: Analysis in two prospective series (ATENA, CLARITY) L. Pierot, C. Cognard, L.

Remodelling? Technique initially designed for the treatment of wide neck aneurysms What is a wide neck? – > 4mm (Zubillaga, 1994) – Sac / collet < 2? 1.5?
Remodelling: technique Balloon placed in front of the aneurysm in the parent vessel Inflated during deposition of each coil Deflated between each coil Removed at the end of the procedure
Remodelling: technique variants How to place the balloon? – In the parent vessel, in front of the neck – In the neck – Angle of attack Remodelling 2 balloons
Important issues Is the remodelling technique associated with a higher risk of complications and morbi- mortality compared to standard coiling? Are anatomical results improved by the remodelling technique?
Conclusions Safety of the remodelling technique is similar to standart coiling in both ruptured and unruptured aneurysms (ATENA, CLARITY, Literature review). The remodelling technique seems to be more efficacious than the standart coiling on anatomical point-of-view. The remodelling technique can be widely used in the treatment of ruptured and unruptured aneurysms.
